We propose now to ascertain the position of the American churches in relation to the slavery question. The most of them have been compelled to take some action on this exciting subject. We shall notice, more especially, the late action of various denominations, both for and against slavery, that the reader may know precisely where each branch of the _Protestant_ churches of this country, may be found. We do not deem it necessary to exhibit the relation of the _Catholic_ church to slavery. We may remark here, however, by the way, that this church, if it be proper to call it a church, is soundly pro-slavery, and is, in America, as it is everywhere else, a staunch advocate of oppression. Few Protestant churches excel the Catholic in slaveholding. PRESBYTERIAN (OLD SCHOOL.) The Presbyterian church (O.S.) stands fully and unequivocally on the side of the oppressor. It is true that a few earnest anti-slavery men may be found in this denomination, but their influence upon it is scarcely felt. They are not able in the least to modify the decided, unfaltering pro-slavery position maintained by the General Assembly. So far as I know, the most ultra friends of slavery are perfectly satisfied with the late ecclesiastical action and influence of this church. It makes no pretensions to anti-slavery. The slaveholder is welcomed to its communion, is authorized to preach and is elevated to the highest posts of honor. At the last General Assembly fifty slaveholding presbyteries were represented. The place of meeting was Charleston, South Carolina. Dr. Lord, author of a celebrated sermon in support of the fugitive slave law, was elected moderator. The General Assembly of 1845, by a vote of 168 to 13, "Resolved, That the existence of domestic slavery, under the circumstances in which it is found in the southern portion of this country, is no bar to Christian communion."
